What do you mean by "its legitimacy?" If it fits, it fits. 1 b2 can be a groovy set to use. It doesn't matter if it has been used often by other people unless you just want to personally expand your perception on the scale. However, if you just want references to show people that it can be groovy... why not just use the tool strapped on you and in your hands? Your bass! Groove the scale out and show your fellow cats it's kickin'. If you can't personally groove the scale hard, then why try and get other people to?
